Biotechnology — Previous-Year Question Papers

How is the Biotechnology paper set, and which topics repeat? Knowing the exam pattern and the most-asked topics is the fastest way to prepare with past papers.

Frequently examined in Biotechnology: Michaelis-Menten enzyme kinetics, Km, Vmax and inhibition, Central carbon metabolism: glycolysis, PPP, TCA cycle and key intermediates, Metabolic pathway enzymes and pathway identification, Biochemical analytical techniques: SDS-PAGE, western blot, chromatography and centrifugation, Mendelian genetics and probability in genetic crosses, Linkage mapping, recombination frequency and gene order. See the full ranked list with how often each topic appears on the Biotechnology subject page.

How to use past papers: Solve the last few years of papers under timed conditions, mark every topic you miss, and revise those first. The pattern above tells you how marks are split across sections.

Frequently asked questions

Where can I download Biotechnology previous-year question papers?
